Definitions

  • the invention relates to a reactor for irradiating ultraviolet light in a fluid reaction medium.
  • the reactor consists of at least one housing which encloses a tubular cavity with a radiation source for generating ultraviolet light and an inner tube, which forms with the housing a particular annular irradiation space, wherein the irradiation space at least with an inlet and an outlet for the reaction medium is connected and flows through the reaction medium in the longitudinal direction of the tube, and wherein the irradiation space comprises means for generating an additional radial flow guidance of the reaction medium.
  • the sterilization of liquid media is an essential prerequisite for the use of biotechnological and food technology production processes.
  • the objective is the reliable and complete depletion of microorganisms and / or viruses while at the same time preserving the valuable substances as far as possible.
  • Both the feedstocks e.g., nutrient media for fermentations
  • end products e.g., dairy or pharmaceutical drug proteins
  • shelf life extension for the application of sterilization techniques while their use in the pharmaceutical industry is regulated by strict quality assurance requirements.
  • several, based on different principles of action virus inactivation steps are required, which ensure a virus depletion by at least four powers of ten.
  • the need to ensure virus safety also applies to pharmaceuticals produced by genetic engineering.
  • the aim of the UV radiation is the mutagenic change of the genetic material of microorganisms or viruses that lose their reproductive capacity above a minimum radiation dose.
  • the object of the invention is to develop a safe and optimally effective device for irradiation with UV light for this purpose.
  • a further negative influence is the unfavorable residence time behavior of the liquid films, which according to the usually only small penetration depth of the UV radiation into the reaction medium are necessarily very thin and thus laminar, in which an exchange transversely to the main flow direction is by definition omitted.
  • the near-wall layers dwell much longer than the layers further away from the wall because of the velocity profile decreasing linearly to the wall down to zero.
  • the mean residence time of the film must be increased. However, this leads to increased radiation exposure and thus to greater damage to the products.
  • a UV ring-gap reactor of conventional design consists of a tubular metal housing into which a quartz tube containing a rod-shaped UV radiator is embedded, so that an annular gap-shaped space is formed.
  • the reaction medium flows only in the axial direction through the annulus, which is also not advantageous in view of a good mass transfer similar to the thin-film reactors.
  • the reactors of the type mentioned are also suitable for the treatment of virus-contaminated protein solutions, when the irradiation room over its length means for additional radial flow guidance of the reaction medium and in particular, if in relation to the diameter of the housing a certain reactor length is not exceeded.
  • the proposed L / D ratio should preferably be less than 100.
  • the object of the invention is to provide apparatuses of the type mentioned above with an optimized and more uniform mixing behavior for the reaction medium.
  • the invention relates to a reactor for irradiating ultraviolet light in a fluid reaction medium with a housing which encloses a tubular cavity, with a radiation source for generating ultraviolet light and an inner tube, which forms with the housing a particular annular irradiation space, wherein the Irradiation space is at least connected to an inlet and an outlet for the reaction medium and is flowed through by the reaction medium in the longitudinal direction of the tube, characterized in that the irradiation space comprises means for generating an additional radial flow guidance of the reaction medium.
  • the device (reactor) for irradiating UV light in liquids is characterized by its optimal and uniform mixing behavior by a better mass transfer, whereby a safe and effective sterilization is achieved.
  • the device integrates well with existing equipment and is easy to clean. Another advantage is the compact design of the device.
  • the device is characterized in that special flow conditions are generated in an annular gap channel which is permeable to UV light and cause an intensive mass transfer over the entire channel length. It consists for example of a UV radiation source, which may be surrounded by a quartz protection tube (radiator cladding tube), and a transparent to UV light product channel (irradiation space) through which the reaction medium flows.
  • the special feature of the irradiation room is an intensive, uniform cross-mixing over the entire length perpendicular to the main direction of the product flow as well as a narrowed by turbulent product flow residence time distribution.
  • Cross-mixing ensures that the liquid layers, which are more remote from the radiation source and receive little or no UV radiation, especially in strongly light-absorbing media, exchange intensively with the UV-irradiated layers near the radiation source.
  • This is e.g. achieved by a special flow guidance in the device through which a plurality of cascaded, quasi-cellular circulation flows is generated.
  • the secondary flows are generated by stirring, by the flow of internals or by the passage of spiral channels.
  • the reactor is designed such that the radiation source is arranged in the inner tube and the inner tube is permeable to the ultraviolet light.
  • the inner wall of the housing particularly preferably has a coating with a material which reflects UV radiation.
  • the radiation source of the reactor is located outside the housing and the housing is transparent to the ultraviolet light.
  • the wall of the inner tube then particularly preferably has a coating with a UV radiation-reflecting material.
  • a preferred means for generating an additional radial flow guidance of the reaction medium is a cylindrical stirrer, in particular a cylindrical stirrer with preferably 2 to 10 stirrer blades, which is arranged in the irradiation space.
  • the reactors with stirrer which are preferably used for gentle UV treatment, advantageously use the formation of radial and Taylor flows or combinations of the two for cross-mixing.
  • Taylor vortices arise in cylinder stirred reactors by driving the inner cylinder.
  • the UV irradiation can also be done by the static outer quartz glass jacket, around which the UV tubes are positioned. This device requires numerous UV emitters and thus causes a larger operating effort.
  • of the total supply of UV radiation only that portion can be used almost lossless, which is recorded at right angles to the glass wall, while the radiation is significantly attenuated in the other directions of irradiation by refractions.
  • a much simpler solution for building up an internally driven tangential flow is provided by a preferred cylindrical stirrer with preferably 2 to 10 stirrer blades rotating around the inner cylinder with a small wall distance of preferably 0.2 to 20 mm.
  • the stirring blades having a width of preferably 0.5 to 30 mm can be e.g. through cavernous cuts out of a thin-walled precision tube.
  • the means for generating an additional radial flow guidance of the reaction medium and the irradiation space is formed by a helical tube which is permeable to UV radiation and flattened in cross-section.
  • the helical tube has a rectangular (preferably with rounded corners), oval or semicircular cross-section.
  • Spiral tube flows can preferably also be produced by working out spiral turns from one of two cylinders which can be pushed into one another in close proximity to one another.
  • a further preferred subject of the invention is therefore a reactor, which is characterized in that the means for generating an additional radial flow guidance of the reaction medium is formed by one or more, in particular helical, channels which are arranged on the inner wall and / or the outer wall of the irradiation space, are preferably arranged circumferentially on the outer wall of the irradiation space.
  • the channels have a rectangular (preferably with rounded corners), trapezoidal or semi-circular cross-sectional profile.
  • the channels have, in particular, a depth of 1 to 100 mm, preferably of 2 to 50 mm, and an average width of 1 to 200 mm, preferably of 2 to 50 mm, in the cross-sectional profile.
  • the helical depression with a depth of cut of preferably 1 to 40 mm from the outer cylinder is worked out.
  • Spiral tube flows can also be produced by means of specially shaped tubes, which are pulled over a cylinder according to the invention. Consequently, a reactor is also preferred in which the outer wall of the irradiation space and the channels are formed by a corrugated hose.
  • a favorable distance between hose (outer cylinder) and glass tube is at a width of the helical channel of 2 to 20 mm, in particular from 0.1 to 1 mm.
  • the Dean vortices induced by the spiral tube flow are completely dispensed with.
  • 10 to 100 mm high annular gap chambers are preferably formed by additional internals with a clear width of preferably 3 to 15 mm and a height of 2 to 6 times the width, the upper and lower limits relative to the chamber depths a gap distance of preferably 5 to 40% to the inner glass cylinder possess.
  • the product stream is accelerated to a higher velocity as it passes the boundaries in a slit flow.
  • This product stream which is introduced as a free jet into the next chamber, sucks in liquid surrounding the inlet and accelerates it while reducing its own speed. This induces a strong secondary vertebra.
  • the reactor may be designed so that the inlet is formed so that the reaction medium enters the irradiation space tangentially, radially or axially.
  • the embodiment with tangential inlet is particularly preferably used, in particular in the design with an open, continuous irradiation zone.
  • At least one UV sensor with measuring device for measuring the UV intensity of the radiation source is attached to the reactor, in particular in the upper or lower region of the reactor, e.g. near the inlet and / or outlet.
  • a further preferred variant of the reactor has at least one UV sensor with measuring device for measuring the UV intensity in the irradiation space, in particular in the lower or upper area of the reactor, for example in the vicinity of the inlet and / or the outlet of the reactor.
  • the use of the reactor is directed to a variety of different applications for UV irradiation and / or sterilization of liquids.
  • the invention further provides for the use of the reactor according to the invention for the irradiation and sterilization of fluid media and in particular microorganisms and / or viruses containing liquids, preferably foods, particularly preferably milk or fruit juice products or drinking water, chemical or pharmaceutical products, particularly preferably virus vaccines, genetically engineered drugs or proteins, eg Active substances or proteins from transgenic animals or plants and from blood plasma or blood plasma derived products.
  • fluid media and in particular microorganisms and / or viruses containing liquids preferably foods, particularly preferably milk or fruit juice products or drinking water, chemical or pharmaceutical products, particularly preferably virus vaccines, genetically engineered drugs or proteins, eg Active substances or proteins from transgenic animals or plants and from blood plasma or blood plasma derived products.
  • the UV reactor according to Figure 2 and Figure 2a consists of a centrally installed UV lamp 1 (Hg fluorescent tube) with the outer diameter of 25 mm and the length of 850 mm, which can be inserted and removed through an upwardly opened quartz glass jacket 2 (inner quartz glass tube) with inner diameter 26 mm without product contact.
  • the open side of the tube 2 is properly sealed by an O-ring 11 in the head cover 17 sterile technology.
  • To the glass tube 2 rotates at a small distance of 0.5 mm reinforced with 8 stirring blades anchor agitator 6. This is stored in the head cover 17 through a sliding bearing 18 and in the bottom cover 16 by a centering tip 7.
  • the drive takes place by means of magnetic coupling, in that the power provided by an external magnetic stirrer 10 is transferred to a counter-magnet 8 mounted transversely to the stirrer shaft 5 in a contact-free and thus sealless manner.
  • the axisymmetric position of the tube 2 is secured by means of a centering pin 9, which is guided within the shaft 5.
  • the annular gap 26 (irradiation space) of 5 mm, in which the inactivation reaction takes place, is bounded inwardly by the outer wall of the tube 2 and outwardly through the optionally with four 3 mm wide baffles 12 reinforced inner wall of the jacket tube 15, at both ends flanges welded to the attachment of the bottom 16 and the head cover 17.
  • the product is fed at a throughput of 150 - 300 l / h in the neck 13 of the bottom cover and withdrawn at the head cover 17 via pipe 14.
  • the cylinder agitator 6 with 8 blades in the form according to FIG. 3 is made from a precision tube with an outer diameter of 31 mm and a wall thickness of 0.8 mm by cutting out 16 cavernous recesses. For reasons of stability, the recesses do not extend continuously over the entire length of the stirrer, but extend as far as the web connections 19.
  • the anchor stirrer 6 is connected to the stirrer shaft 5 via a disk 21. The reaching into the shaft 5 centering hole 20 is used for centering the bottom closed tube 2. The stirrer in turn is centered in the bottom cover 16 via a centering tip 7.
  • sealless impeller drive for the anchor agitator 6 according to the FIG. 4a (Section BB) and 4b (section AA) consists of 4 mounted on the agitator shaft 5, convex curved paddle wheels 23 with a height of 10 mm. The diameter of the paddle wheel is 39 mm.
  • the drive is effected by the tangentially introduced into an upstream annulus 24 product, which is passed over four against the interior tangentially employed column 22 with a gap width of 0.8 mm on the drive blades.
  • the UV reactor according to Figure 5 and Figure 5a consists of a UV lamp 1 with the diameter 25 mm, around which a quartz glass tube 27 is wound with a half-round cross-section of 8 mm diameter and 4 mm radius at a small distance.
  • the UV reactor according to FIG. 6 and FIG. 6a consists of a UV lamp 1 with the diameter 25 mm, around which a quartz glass tube 27 with a rectangular cross-section of 8 mm width and 4 mm depth is wound at a small distance.
  • secondary vortices 4 so-called Dean vortices, are induced, which result in a circulation of the material to be irradiated in the tube 27.
  • the UV reactor according to Figure 7 and Figure 7a consists of a UV lamp 1 with surrounding, continuous, at the top 17 and bottom cover 16 with O-rings 11 sealed against the reaction space 26 quartz glass tube 2, which is overflowed on the outside of the product spirally.
  • the contour of the spiral flow is predetermined by the channel 25 in the outer cylinder 15.
  • a round thread is cut in the outer cylinder 15 with a depth of 4 mm and a width of 6 mm.
  • the smallest distance between glass tube 2 and cylinder is 0.5 mm. This gap allows to reduce the fouling problem to enter a part of the product flow as a free jet 29 in the overlying flow channel.
  • the UV reactor according to FIG. 8 and FIG. 8a consists of a UV emitter 1 with surrounding, continuous, at the top 17 and bottom cover 16 with O-rings 11 sealed against the reaction space 26 quartz glass tube 2, which is overflowed on the product side in the axial direction. Due to the sawtooth contour of the channels 25 'of the outer cylinder 15, a plurality of delimited annular gap spaces with a height of 30 mm and a gap width of 4 mm for the formation of the secondary vortex 4 are created (see FIG. FIG. 8a ). The secondary vortices are driven by free jets 29, which are produced in the 0.7 mm wide annular gap when the product flow enters the channels 25 '.

The axial free jets are created in 0.7 mm wide annular gaps on the inner and outer circumference of the chambers.
  • the UV reactor according to FIG. 10 (Partial view) is opposite to the reactor according to FIG. 7 modified so that the gap between glass tube 2 and outer cylinder 15 is omitted.
  • a UV sensor 30 is mounted, which directly measures the UV radiation emitted by the UV emitter 1. This is used e.g. allows regulation of the UV intensity.
  • a second UV sensor 31 is arranged in the irradiation room in order to be able to observe "fouling processes" in the reactor.
